so it sounds like her youngest sibling passed away and at some point one of her parents remarried. I’m assuming it was her father that remarried and that she comes from a wealthy family. It also looks like she was in the car with her step sibling and may be some altercation happened and they got into a car accident. There was a major betrayal somewhere, but I don’t know if it was all that step siblings doing, a mother & daughter, or something else.
